A CORPORATION OF CONNECTICUT VALVE OUTLET FIXTURE Application filed January 11, 1932.

My invention relates more particularly to valves used in connection with outlet fixtures for pneumatic systems, to which xtures a lengths of hose are attached which are employed for pneumatic cleaning purposes, and an object of my invention, among others, is the production of an outlet fixture equipped with means whereby it will readily adjust itself to various angles which the surface to which the xture is applied may present.

One form of a. fixture embodying my invention and in the construction and use of which the objects herein set out, as well as Others, may be attained is illustrated in the accompanying drawing, in which` Figure 1 is a face View of a. fixture embodying my invention.

igure 2 is a view partly in vertical section on a plane denoted bv the dotted line i '2.0 2 2 of Figure 1.

Figure 3 is a. similar view on a plane denoted by the dotted line 33 of Figure 1, and

Figure 4 is a view in horizontal section on y '25 a plane denotedy by the dotted line 4-4 of Figure 1.

My invention, herein illustrated and described, is particularly adapted for use in connection with an outlet fixture of the type shown in United States patent to Ira H. Spencer, N o. 1,717,471, dated June 18, 1929, the present device, in fact, being an improvement upon the fixture of said patent.

In the accompanying` drawing` the numeral 5 denotes the base-board of a room which board has an opening 6 therethrough to which my improved fixture is applied, and which extends through said opening, the inner end of the fixture being connected with a 'i' 7 of a conduit 8 forming a part of the pneumatic system commonly installed in buildings for cleaning purposes, and as particularly set out in the said Spencer patent.

In installing these systems it often happens that the base board 5 is irregular as to its outer face against which the fixture is placed, or that the face of such base-board is located at an angle to the floor or not parallel with the conduit, with a resultthat the plate resting against such base-board will not rest Serial No. 585,915. i

against the board on all sides. lt is to overcome this defect and enable such plate to be placed tightly against the board on all sides that the present invention has been devisedy` r and in carrying out this purpose I provide a 5 union 9 that is screw threadedly engaged within an opening in the lateral projection of the T 7. This union 9 has a recess 10 to receive the nipple on the end of a. pipe to be i, attached to the fixture, and the union also has on its outer surface a spherical seat 11 for a purpose to be hereinafter described.

A valve support comprising a case in which the valve is located is attached to the unioni 9, such support in the particular construc- 6" tion herein shown comprising a Wall plate 12,

a. back plate 13 and a front plate 14. These plates are preferably of oval shape,vthe back plate having a peripheral flange 15 forming a recess within which the wall plate is located and the front plate having a somewhat broader peripheral flange to form a recess 16 for a pivotally mounted valve 17 located in said recess between the front and?. back plates and as shown in Figures 3. and` 4 of the drawing. Said valve is secured to a spindle 1S rotatably mounted in aI raised portion 19 on the face of the plate 14, a spring 2O having one end engaged in a slot in the case and its other end engaged with a slot B in the valve, as shown in Figure 3, surrounding said spindle and acting to hold the valve normally in its closed position.

A hub 21 projecting from the face of the .f -r front plate forms a seat for a flap valve 22 B that is pivotally attached to ears at one side of the hub, and as shown in Figures 1, 2, and 3 of the drawing. A handle 23 projects laterally from the end of the spindle 18 as a- A means for manually operating the valve 17, 90 particularly to open it, said valve, in ordinary operation, being' retained in its closed position until a nipple 24 on the end of a hose 25 has been inserted in the hole in the y hub 21 with its end against the valve 17 after 9" the flap valve has been rai sed. The handle 23 is then operated to open the valve 17 and the nipple is pushed inwardly to seat its end against the shoulder at the bottom of theV recess 10. rThis prevents any sudden inrush "100 VV:a

of air from the outside through the opening into the fixture such as would cause objectionable hissing or screeching sounds.

The plates 12, 13 and 14 may be secured together either in pairs, or otherwise, in any suitable manner, as herein shown screws passing through each of the plates and into the base board 5 being employed, and it is very essential that the wall plate 12 as well as the flange 15 on the back plate shall rest squarely against the surface to which the fixture is secured. To effect this purpose a hole is formed through the wall and back plates and the edge of each of these holes is curved in the direction of depth of the plates, this curve preferably being of spherical shape to fit the curve or spherical seat 11 on the outside of the union 9. This provides a ystructure by means of which the two plates 12 and 13 may be assembled with the union and seated squarely against the surface of the base board or other supporting member, and the ioint between the union and the two plates will be maintained in an air tight condtiion, which is absolutely essential to the proper operation of the system, as if a leak is present between said plates and the union the operation of the system will be impaired and objectionable noises are liable to ensue as a result of the leak. Said plates are relatively movable to permit them to seat themselves against a supporting surface, suicient space being left between theplates to effect this purpose. In assembling the structure the two plates are placed upon the union from opposite ends thereof. and are then secured to the supportinar surface as hereinbefore described.

I claim:

1. An outlet fixture including a union adapted to be attached to a conduit. sai d union having a curved seat, a valve support comprising a. valve case. said support including a plate having a. hole with a curved edge to receive and fitting said seat, and a valve mounted within said case.

2. An outlet fixture including a union having a curved seat. a valve support comprising a valve case, said support including two plates each having a hole with a curved edge to receive and fitting said seat, and a valve mounted within said case.

3. An outlet fixture including a union adapted to be attached to a conduit, said union having a spherically shaped seat on its outer surface, a valve support comprising a valve case, said support including two plates each having a hole with its edge shaped to receive and fitting said seat, and avalve mounted in said case.

4. An outlet fixture including a union adapted to be attached to a conduit, said union having a spherically shaped seat on its outer surface, a valve support comprislng a valve case, said support including two plates each having a hole with an edge shaped to fit the seat on said union, said plates being attached to said union from opposite ends thereof, and a valve mounted in said case.
